OpenShift OKD Cluster First, set cluster name: CLUSTER_NAME="cluster-1" Now, create configuration files: Note The sample output below is showing the AWS provider, but it should work the same way with rkload-certs.sh This saves the certs (ca.crt, tls.crt, tls.key) to the current directory. These files need to be copied to your external workload.

This will extract the keys that Cilium is using to connect to the etcd in the local cluster. The key files are wri�en to config/.*.{key|crt|-ca.crt} Repeat this step for all clusters you want The key files in config/ and the secret represented as YAML are sensi�ve. Anyone gaining access to these files is able to connect to the etcd instances in the local cluster. Delete the files a�er the http://127.0.0.1:31079 - [...] Check for level=warning and level=error messages in the Cilium log files Run a bash in a Cilium and validate the following: Rou�ng rules matching on fwmark: ip rule list
